INLPROVEMENT IN STEAM-ENGINE STEAM-CHESTS.

The Schedule referred to in these Letters Patent and making part of the same.

To all '1071.mn'itmay couceofnf:v y

Be it known that I, WILLIAM STAMP, of Susquehanna Depot, in the county of Susquehanna, and State of Pennsylvania, have invented a new and improved method of making j oints'for alll vessels wherein steam or water, is confined, the same being cylinder, steamchest, pipe, or other contrivance for holding steam or.

Figure 3 is a transverse section of steamchest,where B represents wire inserted in base, chest, and cover.

The operation, then, is this: Wire, -drawn as shown in Figure 4, being inserted, with the concave side down, in groove prepared for that purpose, i'sthen properly driven and hammered to thoroughly ll the groove, which, being faced o, as usually done, the joint is iinished.

The'value of this joint is twofold: iirst, vthat this economical' use of a non-corrosive metal ring in joints, between cast vor wrought-iron suifaces, preserves the same intact for a much greater length of time than they otherwise could be preserved; and, second, the joints so made are, from the first, nearer perfect, both from the greater density of the metal used, and `its greater expansive quality.

The construction of the wire packing, inserted in both surfaces of the joint to be made, substantially as herein described'. l

WILLIAM STAMP.
